THE HIGH‐ AND LOW‐ENERGY PHOSPHATE ADSORBING SURFACES IN CALCAREOUS SOILS

Summary The two‐surface Langmuir equation was used to study P adsorption by 24 calcareous soils (pH 7.2‐7.6; 0.8‐24.2 per cent CaCO 3 ) from the Sherborne soil series, which are derived from Jurassic limestone. High‐energy P adsorption capacities ( x ″ m ) ranged from 140–345 μg P/g and were most cl... View More
